C. Interphase - This phase have no change in cell except its size as it grows and enlarges itself.
D. Telophase - formation of a nuclear membrane around chromosome set to separate the genetic material from the cytoplasm.
E. Metaphase - visible chromosomes, removal of nucleus and chromosomes present in cytoplasm.
F. Anaphase - replicated chromosomes are separated and move towards opposite poles.
In Drosophila, the genes for body coloration and eye size are on different chromosomes. Normal-colored bodies are dominant to ebony-colored (very dark) bodies, and normal-sized eyes are dominant to eyelessness. Line A is true breeding for normal bodies and normal eyes, whereas line B is true breeding for ebony bodies and eyelessness. From an F 2 cross between lines A and B, 800 flies are scored. How many F 2 flies are expected to have normal body color and to be eyeless
Answer:
150.
Explanation:
150 flies are expected to have normal body color and to be eyeless in F2 generation. The reason for that population is the ratio of the species produced. The ratio of the species are 9:3:3:1. Ratio 9 refers to first parent while 1 refers to second parent and the middle 3's represent the hybrid formed. So the population of first parent is 450 and population of second parent is 50 while the population of two hybrids are 150 each.

1. Explain why some heterotrophs can be described as both a primary consumer and a secondary consumer. What are these heterotrophs called
Answer:
Heterotrophic species that eat organisms from different trophic levels
Explanation:
Humans are examples of primary and secondary consumers because we are able to eat different types of living forms, thereby acting in the food chain as primary consumers (eating plants) in certain conditions and as secondary consumers (eating animals) in different conditions. Many heterotrophic organisms act at different levels by feeding primary producers and primary consumers based on specific trophic strategies. In consequence, the classification between primary and secondary consumers is arbitrary since it varies according to the trophic strategy adopted by the organism.

How can changes on earths surface affect changes below surface
Answer:
There are several changes that occur on the earth's surface but also affects the changes below the surface, some of them are as follows:
When rainfall occur on the sandy surface on earth, it looses the soil under the surface and can cause landslides.Imbalance in the food chain above or on the earth surface can affect the nutrient quantity below the surface that is essential for soil bacteria and other microorganisms.Deforestation can also loosen the soil and soil under surface can shift its position.Use of chemicals on agriculture surface can lead to change the fertility of soil below the surface.In the body, the homeostasis of which element is related to properties of bone?
Answer:
Homeostasis of calcium
Explanation:
Bone homeostasis is a complex process by which osteoclasts resorb bone and osteoblasts engage in new bone tissue formation. This sequence has to be controlled and and planned in order to maintain skeletal integrity of bones.
Calcium homeostasis is related to bones physical properties because play a crucial role in skeletal muscle maintenance by acting as mitogen-activated protein kinase (MAPK) signaling effector and other different pathways that is responsible for regulating cell proliferation, differentiation, and cytoskeletal restructuring .
In the body, the homeostasis of Calcium element is related to properties of bone
What is Bone homeostasis?Bone homeostasis is defined as the dynamic equilibrium which is maintained by the regulatory functions of the three major bone cells, osteoclasts, osteoblasts and osteocytes, as long as the activities of these cells are properly adjusted, therefore the net bone mass is maintained.
Calcium homeostasis is related to the physical properties of bones as it plays an important role in skeletal muscle maintenance by acting as an effector of mitogen-activated protein kinase (MAPK) signaling and various other pathways that regulate cell proliferation, differentiation and cytoskeletal reorganization.

The genomic DNA of an organism has a base composition of 40% C-G base pairs and 60% A-T base pairs. Assuming a random sequence of bases, what is the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3'?
Answer:
The correct answer is (0.2)^4.
Explanation:
Based on the given information, the given genomic DNA is A-T rich, and the base pair composition is C-G = 40 % and A-T = 60%. Therefore, as per Chargaff's rule, Each C and G will possess 20%, and each A and T will possess 30%.
Therefore, the probability of each base will be,
C = 20/100 = 0.2
G = 20/100 = 0.2
A = 30/100 = 0.3
T = 30/100 = 0.3
Now the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3' will be 0.2 * 0.2 * 0.2 * 0.2 = (0.2)^4.
36% of your study population are h recessive for fingernail growth rate. Using the Harvey Weinberg equilibrium equations (P+Q = 1 and P2+2PQ+Q2 = 1), calculate the frequency of h dominants and heterozygotes in your population.
Answer:
frequency of h dominant = 16%
Frequency of heterozygotes = 48%
Explanation:
The computation of frequency of h dominants and heterozygotes in your population is shown below:
Since it is mentioned that
q^2 = 36%
So q = 0.6
And
p + q = 1
So, the p is 0.4
Now the frequency of h dominant is
= p^2
= (0.4)^2
= 16%
And, the heterozygotes in the population is
= 2 × p × q
= 2 × 0.4 × 0.6
= 48%

The reason why bacteria can infect a person very quickly is because of the process of binary fission.
What is binary fission?
Binary fission is defined as the reproduction process that is found in prokayotes such as the bacteria.
The binary fission involves these steps:
Replication of DNA (deoxyribonucleic acid),Growth of a cell,Segregation of DNA and Splitting of cells.The final stage which is the splitting of cells leads to the formation of many daughter cells of the parent bacteria cell which can eventually led to infection.

1. Hypothesize in what type of environments it would be advantageous for a protist to be autotrophic, heterotrophic, or mixotrophic.
Answer:
See below
Explanation:
Protists fall into the category of eukaryotes. They are diverse in nature and typically are found to be single celled organisms containing very organized structures.They are classified based on what is their source of nutrition.
Autotrophic - capable of photosynthesis to produce their own food, so an environment where sunlight, CO2 and water is available.
Heterotrophic - feed on other organisms , an environment where prey is plenty and very limited or no access to sunlight.
Mixotrophic - a combination of the above two, an environment with all of the aforementioned factors present.

How does the vessel diameter of the afferent arteriole change in order to decrease glomerular hydrostatic pressure (GHP) and restore the glomerular filtration rate (GFR) to normal
Answer:
The afferent vessel will generate vasodilation, that is, increase its diameter to generate a stirring effect in the glomerulus, promote glomerular filtration and decrease pressure in it.
Explanation:
The renal glomeruli are in charge of filtering the blood.
They have an efferent vessel that collects the blood to be filtered and an afferent that is in charge of returning it to the bloodstream of systemic circulation.
When the pressure of the glomerulus is very high, the glomerular filtration rate is increased and it needs to be regulated, that is why the afferent vessel undergoes vasodilation to decompress the glomerulus pressures and thus regulate the filtration rate by decreasing it.

Compare and contrast the contributions of Neel, Pauling, and Ingram to our understanding of the genetic and molecular basis of sickle cell disease (SCD).
He demonstrated that SCD and sickle cell trait were due to the presence of abnormal 8-globin polypeptides in red blood cells. He demonstrated that the electrophhoretic mobility of B-globin from patients with SCD was different from that of healthy individuals. He demonstrated that both parents of multiple patients with SCD had low levels of sickled red blood cells. He hypothesized that SCD was a recessive trait and that the parents of patients with SCD would be heterozygous carriers. He demonstrated that the difference between B-globin polypeptides in individuals who were healthy and those with SCD is an amino acid substitution. He performed a peptide fingerprint analysis on B-globin from individuals with 84 84 and 89 88, which identified the segment of B-globin that was changed by the BS mutation.
